is there a chance of getting NLA working ? As we currently have two terminal servers and it make the users login in twice if the first server has to many sessions active, we are looking at adding another terminal server which means that they would potentially have to login three times.

i've just tried to login with the load balance option specified and its still making me log into the first server and then the second one. When looking at the Microsoft Rdp file in notepad the server that it connects to is the broker server which then somehow forwards the connection to the correct terminal server. There is a parameter in the Microsoft Rdp file called: use redirection server name:i:1 may have something to do with it.
